Abstract

This study aimed to determine the effect of the use of problem-based teaching model on the critical thinking skills and effect of the use of problem-based teaching model on the creative thinking skills of students on environmental pollution materials. The research was conducted at SMAN 2 Magelang. The research method used was a quasi-experimental design with nonrandomized control group pretest-posttest. The data analysis used the t test. The result of the calculation of the posttest average of the difference between the two groups for critical thinking skills shows the calculated value of 2.45 and ttable with the significance level of 0.05% with 62 df = 2.00, while for the ability to think creatively the calculated value of 3.43 shows the ttable with the significance level of 0.05% with 62 df = 2.00. This shows that t > ttable. This means that the alternative hypothesis (Ha) is accepted and null hypothesis (H0) is rejected. Thus, there is an effect of the use of problem-based teaching model on the critical and creative thinking skills of the students on the concept of environmental pollution.
